The actual reported bug was fixed at some point during the refactoring
of the Wayland backend. This is only a bit of tidying. Updating the
cache before emitting events is always a nice thing to do.
Closes#2046
glfwGetKeyName emitted GLFW_INVALID_VALUE when passed GLFW_KEY_UNKNOWN
and any scancode not associated with a key token on that platform.
This causes physical keys with no associated key token to emit
GLFW_INVALID_VALUE when the key and scancode are passed directly from
the key event to glfwGetKeyName. This breaks the promise made in the
reference documentation for glfwGetKeyName.
This commit removes that error for the whole range of valid scancodes.
Fixes#1785
This adds window hints for the initial position, in screen coordinates,
of a window. The special value GLFW_ANY_POSITION means the window
manager will be allowed to position the window.
It is not possible to set window positions on Wayland and GLFW will
always behave as if these hints are set to GLFW_ANY_POSITION.

This avoids glfwCreateWindow emitting GLFW_FEATURE_UNAVAILABLE or
GLFW_FEATURE_UNIMPLEMENTED on Wayland because shared code was calling
unimplemented or unavailable platform functions during final setup.
It also makes it consistent with the final setup of full screen windows.
The code assumed that at least some data would be received via the INCR
mechanism and that, as a result, the string buffer would be allocated.
Bug found by Clang static analysis.
The clipboard string should not be freed on SelectionClear. The user
may have received it from glfwGetClipboardString and it should remain
valid until the next call to a public clipboard string function.
This moves the X11 polling implementation to a separate file where it
can be used by either the X11 or Wayland backend or both.
This code should be POSIX compatible where necessary but will use the
lower latency but non-standard polling functions ppoll or pollts where
those are available.
This commit is based on work by OlivierSohn and kovidgoyal.
Fixes#1281Closes#1285
This uses ppoll for waiting on file descriptors with a timeout, where
that function has been available a while. On NetBSD, which will be
getting ppoll in the next release, the equivalent pollts is used.

There is a seemingly unavoidable race condition when waiting for data on
the X11 display connection, as long as any other thread is also making
Xlib calls. The event data we are waiting for could be read by the
other thread as part of looking for the reply to its request, before our
poll has begun.
This commit replaces the X11 event sent by glfwPostEmptyEvent with
writing to an unnamed pipe. The race condition remains if other Xlib
calls are made on other threads, but glfwPostEmptyEvent should now be
race-free.

The data available on the X11 connection may be a reply or an internal
event for an X11 extension. Previously the check for whether an event
was available for us was done outside waitForEvent. This prevented data
available on other file descriptors from breaking the outer wait loop.
This commit moves the check for whether an event is available into the
wait functions, where there is enough knowledge to limit the check to
the X11 connection.

On Linux, the inotify descriptor was included in the set used for
select, but could not break the outer loop, leading to busy waiting
until timeout or the correct X11 event arrived.
This commit adds a new function for waiting just on X11 events.
Fixes#1872
